This immediately excludes true hypoxemia. (2) There is an obvious mis-match between the PaO2 (which is >>100 mm) versus the pulse oximetry (which is typically ~80-90% saturated).

Historically, arterial blood is predominantly used for blood gas analysis. WebNov 2, 2016 · We’re generally comfortable with a saturation of 88%, but a PaO2 of 55mm may cause concern. The lower number is scarier. This cognitive bias is often seen when ABGs are obtained in patients on mechanical ventilation. For a patient with mild hypoxemia, the PaO2 value will often be surprisingly low.
WebMar 2, 2024 · Blood PO 2 measurements tend to be normal because PO 2 reflects O 2 dissolved in blood, and this process is not affected by CO. In contrast, hemoglobin-bound O 2 (which normally comprises 98 percent of arterial O 2 content) is profoundly reduced in the presence of carboxyhemoglobin (COHb).
